I’m developing an Android app, and my intention is to be able to publish it for Android 2.2+ at least. Currently, I’m limited to Android 4.0+ because of the WebView control being a mess.
The app is largely HTML+CSS+JS+jQuery based.
div.appList shows a list of apps, and when clicked the app should launch. Only there’s some trouble with this; For the list to be scrollable, I have to add overflow: scroll; to its parent. This works fine in Android 3.0+. In Android 2.x the list is still not scrollable.
I said it worked fine in Android 3.0? Well, the scrolling does. Now the problem is that it doesn’t register clicks. If the user taps an item in the list, the click event simply doesn’t get triggered, because, I’m guessing, it’s registered as the user scrolling through the list. Making the list unscrollable again makes the items clickable, but then again, the list is useless because you can only access the top few items.
Everything works fine in Android 4.0+
Any help would be hugely appreciated.

Anything that helps me get it working on an older version is appreciated. The goal is Android 2.x, but if you can help me make it work on 3.2+, I’m already very happy.
overflow:scroll|autodowsn’t work properly on Android 2.X devices.This css rule equals to
overflow:hidden🙂You can’t fix it but you can use plugins to avoid this behaviour e.g. http://cubiq.org/iscroll-4
